    1.1 General Safety 1.1.1 Intended Function and Expected Use: ® ® 1.1.1.1. The KEITH WALKING FLOOR system is a reciprocating slat conveyor primarily intended to load, hold, or unload bulk materials. It can also handle unit loads such as pallets by using special handling techniques and possibly additional safety controls. The system is supplied as a kit primarily intended for installation into mobile trailers or truck bodies. The floor is often loaded through an open trailer top or through the rear doors. ...

  • Page 9: Personal Protective Equipment

    1.1.6.2. Overheated oil can degrade rapidly. Hot oil and the resulting hot surfaces can cause burns. Do not allow the oil temperature to exceed 140 °F [60 °C]. 1.1.6.3. KEITH recommends some or all of the following temperature control measures depending on the circumstances. High duty cycle systems and hot environments will require more control measures.

  • Page 10: Design / Installation Safety

    Follow all pipe, tubing, fitting, and hose manufacturer installation and routing guidelines. 1.2.5.2. Hydraulic piping should be supported and isolated from vibration. Contact KEITH for recommendations on installation. 1.2.5.3. Place protective shrouds around the hydraulic tubing in any areas that may have operators or people frequently nearby.

    1.2.6.5. Do not allow the floor to move material toward the front of the trailer when material is  contacting the front wall. KEITH recommends installing limit switches to prevent this. In the absence of a sensor switch, the operator must be keenly aware of the load position, and the control system must require the operator to hold the run signal in the on position to continue running, such that releasing the run signal causes the floor to stop ...
